GST return filing – 2026 cycle

Regular businesses must file two main returns every month:

• GSTR-1: Details of outward supplies (sales). Due 11th of next month.
• GSTR-3B: Summary return and tax payment. Due 20th of next month.

For composition dealers, GSTR-4 is filed annually (due 30th April).

Key dates 2026: Monthly filers must also file an annual return GSTR-9 by 31st December 2026. Reconciliation statement GSTR-9C is waived for certain turnover limits – check eligibility.

Input Tax Credit (ITC) simplified

ITC allows you to reduce tax payable on sales by the tax already paid on purchases. Conditions to claim ITC in 2026:

• You must possess a valid tax invoice/debit note.
• Goods/services must be received.
• Supplier must have filed GSTR-1 and the details reflect in GSTR-2B.
• ITC can be claimed only if you file GSTR-3B before the due date.

Pro tip: Reconcile your purchase register with GSTR-2B every month to avoid mismatch notices.

Compliance calendar 2026

• Monthly (20th): GSTR-3B + tax payment

Common GST mistakes to avoid

• Mismatch in sales: Ensure GSTR-1 and GSTR-3B figures match exactly.
• Not reversing ITC for non-payment: If you haven’t paid the supplier within 180 days, ITC must be reversed.
